PRODUCTION DATA
A failure in the DC/DC converter is indicated by reading a logic high of the SEC_FAIL bit in the STATUS register. This bit is a latched bit. If any failure of the internal DC/DC converter occurs during device operation, but the DC/DC converter recovers from the failure and operates normally after this instance, the SEC_FAIL bit remains in a logic high state until the STATUS register is read. Reading the status register clears the SEC_FAIL bit. As described in the Start-Up Behavior After Power-Up section, use two consecutive STATUS register read commands to verify correct operation of the DC/DC converter at a given point in time (for example, at device power-up).
